Best travel lens for the fujifilm x a3?
For a Fujifilm X-A3, I'd start with the Fujifilm XF 16-80mm f/4 R OIS WR. It covers about 24-120mm in full-frame terms, which is close to the travel zoom range I'd want, and it has stabilisation and weather sealing. The X-A3 has no stabilisation in the body, so that lens counts for a lot on dim church interiors.
If you want something smaller, the Fujifilm XF 16-50mm f/2.8-4.8 R LM WR is a compact, weather-sealed zoom. For a small fast prime for evenings and food, I like the Fujifilm XF 35mm f/2 R WR. It's a classic pairing with a zoom, as what to pack suggests.
Check what matters for travel before you buy, especially the weight of the camera with its lens.
